When our boys faced the problem of choosing equipment for the new sports season were not differences. All who are engaged in class models AM 1 and AM 2, stopped, as agreed, the scheme proposed with the article “New ice season” (see “M-K” № 3, 1986). And it is clear. Usual off the aeromobile aircraft type with stabilizers a little “boring”, and are given drawings of the machine, more like a real flying car of the future than clean special sports equipment. But most importantly — the benefits of aerodynamics microsony with pusher propeller seemed indisputable. Really liked the logic of their design: improvement of the apparatus is achieved a simplification. This not only reduced aerodynamic resistance to the ideal minimum, but also greatly facilitates the work on the model. And this is when it is very effective.

We offer young modelers-koretnikov apparatus of the class F2A designed to meet the standards of the 1st and 2nd digits. Power circuit model is simplified, as the technology of manufacturing of all parts and components that enables to build such high-speed cord member in the club of the second year. Aerodynamic design progressive, Odnokolenko type. However, to facilitate the piloting system of the engine scheme is supplemented by a small external polacrilin, helping to ensure a smooth transition modes. Developed the stabilizer also serves to simplify flying on takeoff and landing.
The competition, held in Prague in 1983, General attention was attracted by two unusual the box. Despite the fact that over micromachines was just a few days before the official starts, they showed excellent performance, high reliability and ease of use. Defined success primarily to the use of a new chassis developed by Czechoslovak athletes Gaseou P. and W. Zamecnicka. On road performance it is not only not inferior to the best signature models, but on a number of parameters exceeds them.
Processing small plots of land, traditional small-sized motorcycles, in our opinion, is quite difficult. Therefore, we have selected other flowsheet which consists of the following: the power plant is at one end of the plot, and the working body from the opposite edge of the plot moves toward the power unit. The operation can have two options: one course of work, and the reverse is blank; in the presence of blocks — both stroke work.
When these elegant cars appear on the road, they arouse the interest of others. Yes, and how not to draw attention to the two (already “series”!) exactly the same jeep, eye-catching beautiful design and sophisticated rational design! At stops I had to hear the puzzled questions: “What is this machine? The new model UAZ rural version of the “Niva”?” Drivers — and they are also the designers of their ATVs smile: “No, it’s not “field” — “Neva”!” Puzzled by the response of passers-by in disbelief considering the cars and do that in front of them homemade — so a “factory” they look.
Vyklevyvanija corps on the disc or in the inverse matrix has become today an accepted technology of making high-speed RC boat. The shell in this are light, durable and usually require little or no finishing exterior finishing.
Models with a miniature carbon-dioxide engines attract the attention of a growing number of adherents of the small aircraft. This is understandable: like the plant is extremely easy to use, simple, does not require special fuel composition for the operation, allow to make very interesting flying technique available to most modellers, down to the youngest.
The question posed in the title, still have not found a final resolution. The first experiments to replace the traditional sail is a vertical wing, by profiling and design friends of the aircraft, did not bring the expected result. The fact that hundreds of years of its existence, the sail turned into a beautiful multi-device for conversion of wind power into thrust, informing the movement of the ship or the Buer. And it works quite effectively, and acute course, with strong and weak wind, his smooth flow and in the squalls. In addition, the sail is a great tool that allows the helmsman to accurately adjust it in accordance with the selected rate and direction of the wind, its force arising from the roll of a sailboat and other motion parameters.
Offer for fans of DIY table homemade drill press using hand drill. On a solid base is mounted a hollow stand-tube, movably installed inside the stock. On the one hand, he sliced the rack to drive the vertical feed, and with another selected area for connection of the bracket with the guide bar through the longitudinal groove of the rack. On the bracket mounted hand drill and the motor. The drive from the drill motor is belt drive. Vertical supply node provides a mechanism assembled in a separate housing. The external dimensions of the machine depend on the chosen length of the strut and the base; the vertical stroke serves for the size — 100 mm.
Drivers know: after long Parking of the car in the cold to start the engine. At low temperatures freeze even antifreeze! And those who use it for cooling water and drains it at night, lose the opportunity to fill the radiator with hot water — burst frozen in the cold of the cylinder head and the block, and the boiling water almost immediately freezes, forming ice plugs.
